Soldier hiding behind cover in MW3 Season 3.

Modern Warfare 3 Season 3 has arrived bringing with it a range of big changes across both MW3 and Warzone. Here are the full patch notes for the MW3 Season 3 update.

Multiplayer fans have plenty to be excited about as Modern Warfare 3 Season 3 is one of the biggest updates in the FPS game’s history.

It introduces a massive variety of content including new weapons, maps, ranked rewards, balance changes, and even multiple new Perks.

These are all the big changes and the full patch notes for MW3 Season 3.

Six new multiplayer maps

For the first time in Call of Duty history, Modern Warfare 3 Season 3 introduces a staggering six new multiplayer maps, with four arriving at launch and another two following in the mid-season update coming in early May.

The six new maps are as follows:

  • 6 Star
  • Checkpoint*
  • Emergency
  • Grime
  • Growhouse
  • Tanked*

*Coming in Season 3 Reloaded

Classic weapons return

MW3 Season 3 introduces three returning weapons that have featured in past Call of Duty games. As of today, you can use both the MORS sniper rifle from Advanced Warfare and the FJX Horus, a fictional rendition of the MP9, a compact SMG that last appeared in Modern Warfare 3 (2011).

Later in the mid-season update, you’ll also be able to unlock the BAL-27, an iconic assault rifle from Advanced Warfare that once dominated the meta. If it does so again is to be seen.

Although Season 3’s new weapons are mostly throwbacks to older COD games that isn’t entirely the case. The Gladiator melee weapon is also available right now from the Season 3 Battle Pass, providing an extremely mobile blade comparable to the Karambit.

Gameplay

  • Decreased obstructive VFX while firing MWII Weapons to align with MWIII standards.
  • Removed variance from ADS Idle Sway, allowing a predictable sway pattern.

Our next step toward improving the feeling of aiming across all input devices in Modern Warfare III arrives in Season 3. As previously detailed, aimed down sight idle sway discourages players from holding their sights for an extended period of time with a constant, subtle motion that introduces slight inaccuracy.

In today’s update, we’ve removed variance from aimed down sight idle sway, resulting in a predictable and consistent motion curve. This change raises the skill ceiling and rewards players who take the time to master their favorite Weapons.
